My invention relates to blowers. 7 It is the object of my invention toprovide a rigid, quickly assembled, noiseless blower construction, whichwill eliminate all castl ingscustomarily employed in blowerconstructions, and which will eliminate all noise due to the vibrationof the fans and motors.

It is a further object of my invention to provide a common means forsupporting the blower housing and the motor and fan in such a way thatthemotor and fan, while supported from a common support with the ousing,will not touch the housing nor communicate the vibrations thereofthereto.

It is a further ob'ect tov rovide means of easily and quickly, etachaly, mounting the motor with respect to the fan shaft, and resilientlysupporting it in position so that the fan and motor will be properlybalanced.

Referring to the drawin s: V

Thus, the motor and the fan weredirectl as sociated with and mounted upon the drumlike structure of thefan casing. This resulted in very considerable weight. The castings wereexpensive and, in large size I blowers, diflicult to handle because oftheir weight. This necessitated heavy freight charges and, in operation,the vibration of the motor and fan was directly conveyed to the blowercasing and housing. In assembly, much time and labor was lost due to thecomplicated assembly operations between the sheet metal and castingportions ofthe blow or as well as between the fan and motorinstallations.

With this understanding of the prior development in the construction ofblowers, the novel and advantageous features of my invention will beunderstood.

Iselect a scroll casing of sheet metal designated 1 having turned overedges 2 which are U-shaped in cross section.

I then take a side plate, such as 3, and by two operations form a flange4 and an opening- 5. Adjacent this flange 4 I bolt with the bolts 6 aninverted U-shaped horseshoe supportof angle iron designated 7 the feetof which 8 rest upon the ground or any other support.

The other sidewall 9 has an inwardly V formed'flange 10, but as I do notout out this side wall, the bottom 11 of the cup-shaped depression thusformed remains position.-

Asimilar U-shaped angle iron support is mounted adjacent this cup-shapedde ression of the side wall 9 and is desi ate 12. A cross member 13serves to furt er brace this inverted horseshoe reinforcement.

One opening for the blower is at 14 and the other opening is through theflange 4 and the passageway formed thereby.

The fan itself is designated 15 and is mounted upon the fan shaft 16,which is also the armature shaft of the motor 17. This motoris'suspended by flexible plates 18 pref" erably formed of rubber andfabric. These plates are wedge-shaped. They are bolted by the bolts 19to the motor on the motor bracket 20 and by the bolts 21 to the framebracket y 22. The bottom 11 of the side wall 9 is cut away at 23sufficiently for the passage of the to the shaft.

It will be noted that the whole structure is supported on the twohorseshoe reinforcement members but that support of the motor and fan isinde endent of the support for the' casing. The exible resilient members18 provide for the alignment of the motor, its

proper balancing and the absorption of all viration. Any motor of anysize may be mounted, the width-of the fans may be varied utilizing thesame supports: and side walls, merely varying the width of the scroll 1The advantage of interchangeability of this structure'is evident from anexamination of Figures 7, 8 and 9.

. resilientl The shaft 16 may be supported in a bearing 24 in theresilient supports 18 or in the rigid supports 25. This bearing can bemounted in the recess of the cup formed in the side wall while thepulley 26 is mounted beyond the bearing. Thus, the bearing is centrallylocated between the fan and the pulle and a-satisfactory balance can bemaintaine It will be understood that amongst the variations of thisarra'n mission 0 the use of a double inlet casing in connection with'the fan, such fan being supported on either one or both sides an themotor being supported resiliently, if desired. Bearings can also beresiliently supported at one or both ends of the fan shaft either, withor without motors or pulle s.

It will be understoodthat I desire to comprehend within my inventionsuch modifications-as may be necessary to adapt it tovaryin conditionsand uses. a
